Title: Constant current load circuit
Inventor: JIN YOSHIHIRO
IPC: H04M19/00
Filed: 1983-04-08
Abstract: PURPOSE:To obtain a circuit which allows the high-precision, speedy setting of a current value by providing a reference voltage circuit which generates an optional reference voltage from the output voltage of a constant voltage circuit and a constant current circuit which flows a constant current between load connection terminals by using the reference voltage as a control voltage. CONSTITUTION:The constant voltage circuit 6 generates a constant voltage Vx from the output voltage of a subscriber interface circuit 3 between load connection terminals 4 and 5 and sends it to the reference voltage circuit 7. The reference voltage circuit 7 generates the optional reference voltage VR from the voltage Vx and sends it to the constant current circuit 8. The constant current circuit 8 uses the reference voltage VR as the control voltage to flow a current IX proportional to it between the load connection terminals 4 and 5. Therefore, a bias current IBB varies with the output voltage between the terminals 4 and 5, but this is ignored and an invariably constant current IL ( IX) is flowed regardless of the internal resistance, etc., of the subscriber interface circuit 3.

IPC: G11B7/085
Filed: 1994-03-31
Abstract: PURPOSE:To stably and surely make a light beam perform jumping scanning to a desired track by first performing jumping scanning by two tracks to a target track or the adjacent track and then jumping operation by one track, if necessary, in a track retrieval device. CONSTITUTION:When the address of a target track is inputted from the outside, a retrieval circuit 37 fetches the address of a track on which a light beam is currently located from a circuit 26 and calculates a number of tracks N to be crossed and its direction. The circuit 37 sets a jumping direction signal (J) according to the direction. Assuming that the track retrieval operation goes in the direction of inner periphery, the signal J is set to be L. The circuit 37 attains the movement across N tracks by first performing jumping scanning by two tracks N2 times and then performing jumping scanning by one track N1 times. On the other hand, as to the track retrieval operation in the direction of outer periphery, the movement is similarly realized by repeating jumping scanning by one track and jumping scanning by two tracks in the direction of outer periphery. At this time, the circuit 37 sets the signal J to be H prior to the retrieval operation.

Title: Semiconductor laser driver with protective circuit
Inventor: KITACHI NISHIMINE
IPC: H04B10/079
Filed: 1987-03-19
Abstract: PURPOSE:To prevent a semiconductor laser (LD) from deteriorating due to an erroneous regulation at the time of setting an optical output by providing a protecting circuit formed of a CML circuit in a bias circuit and turning OFF a transistor at LD side when a bias current increases larger than an allowable value. CONSTITUTION:A reference voltage is so set in advance that the positive side potential (equal to the emitter potential of a transistors, 7, 9) of a comparator 11 becomes higher than the reference voltage. If a variable resistor 8 is excessively turned erroneously at the time or regulation to tend to supply a bias current to generate an excess optical output to an LD1, the output of the comparator 11 becomes high before it, the base potential of the transistor 9 becomes high, and a bias current flows to the transistor 9 by a CML circuit operation. The transistor 7 is turned OFF at the time or erroneous operation of excess optical output. Thus, it can prevent the LD from deteriorating.

Filed: 1990-03-14
Abstract: PURPOSE:To reduce a consumption current at the time of biasing a data line before the action start of a main amplifier by making a current route to bias the data line separate from ground. CONSTITUTION:A data line bias circuit 2 consists of a switch 6 connected between an internal voltage dropping potential line 7 to possess intermediate electric potential and a data line D/D#. Then, when the switch 6 of a data line bias circuit 2 is turned on, a current flows between the internal voltage dropping potential line 7 to possess the intermediate electric potential and the data line D/D# and the data line D/D# is biased by the intermediate electric potential. Then, the data line bias circuit 2 forms a current route to connect the internal voltage dropping potential line 7 and the data line D/D# and the current route is separated from ground.
